description: >-
  Versioning, deprecation, status and SLA posture for the Athletic Brewing agent commerce
  surface. Athletic Brewing publishes no API lifecycle policy of its own; what exists is
  protocol version negotiation inherited from UCP and MCP, advertised from Athletic
  Brewing's own host.
versioning:
  published: true
  style: dated protocol versions, negotiated at discovery and echoed in a response header
  current: '2026-04-08'
  supported:
  - version: '2026-04-08'
    profile: https://athletic-brewing-company.myshopify.com/.well-known/ucp/2026-04-08

  response_header: 'x-shopify-ucp-mcp-api-version: 2026-04-08'
  mcp_protocol_version: '2025-06-18'
  note: >-
    Two versions are concurrently supported and both are enumerated in the discovery
    document, which is a real negotiation contract — but no policy states how long a
    version is kept, or what notice precedes its removal.
deprecation_policy:
  published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  evidence: >-
    No Sunset or Deprecation response header was observed on the MCP endpoint, and no
    deprecation, EOL or version-support policy page exists on athleticbrewing.com.

    returns HTTP 200 but redirects to the Atlassian Statuspage marketing page and is
    byte-identical to a control request for a nonsense subdomain — a soft 404, not a status
    page.
